Help: Key Fobs Stopped Working
Hey folks -
Just recently, I discovered that my key fob stopped locking and unlocking my C5's doors and hatch. I first figured the fob fell out of sync with the car, so I tried resyncing it. No joy. I tried a new battery. No joy. I tried my other fob. No joy. I tried reprogramming the fobs into the car. No joy.
I suspect the receiver is shot. The odd thing, it's the same receiver that the TPM uses. The TPM works fine. Do you think part of the receiver could have gone south on me?
What do folks think? Any ideas? Or should I expect to have to replace the receiver?
Thanks.

Key remotes are very temperamental and sometimes there's no clear cut explanation.
My guess is the remotes are 6 years old and just from normal wear and tear need to be replaced.
If a vette buddy of yours has a passive design remote you could try to program his remote to your car.
Majority of the time when a member buys a new one his problem is solved.

It's possible the one in the safe could have a run down battery after 6 years. Take the new battery from the other remote and try it in your "safe" remote making sure you install it correctly. It's possible to install the battery upside down.
If you have a friend at a dealership you could stop by and get them to check it out.
